Miti ation:
7. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
Mitigation must be provided for the proposed impacts as specified in the table below. We
understand that you wish to make a payment to the Wetlands Restoration Fund
administered by the NC Ecosystem Enhancement Program (EEP) to meet this mitigation
requirement. This has been determined by the DWQ to be a suitable method to meet the
mitigation requirement. Until the EEP receives and clears your check (made payable to:
DENR -Ecosystem Enhancement Program Office), no impacts specified in this
Authorization Certificate shall occur. The EEP should be contacted at [phone] if
you have any questions concerning payment into a restoration fund. You have 60
calendar days from the date of this approval to make this payment. For accounting
purposes, this Authorization Certificate authorizes payment into the Wetlands
Restoration Fund to meet the following compensatory mitigation requirement:
Compensatory Mitigation
Re uired River and Sub-basin Number
Stream - erennial 3,044 (linear feet) Ca e Fear/03030002
8. Construction Stormwater Permit NCGO10000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division
of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control
program, an NPDES General stormwater permit (NCGO10000) administered by DWQ is
automatically issued to the project. This General Permit allows stormwater to be
discharged during land disturbing construction activities as stipulated by conditions in the
permit. If your project is covered by this permit [applicable to construction projects that
disturb one (1) or more acres], full compliance with permit conditions including the
sedimentation control plan, self-monitoring, record keeping and reporting requirements
are required. A copy of this permit and monitoring report forms may be found at
http: //h2o. enr. state. nc. us/su/Forms Documents htm. ;
9. Culvert Installation
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved
BMP measures from the most current version of NCDOT Construction and Maintenance
Activities manual

such as sandbags, rock berms, cofferdams and other diversion structures shall be used to
prevent excavation in flowing water.
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section
dimensions, pattern, and longitudinal profile) must be maintained above and below
locations of each culvert. Culverts shall be designed and installed to allow for aquatic life
movement as well as to prevent head cutting of the streams. If any of the existing pipes are
or become perched, the appropriate stream grade shall be re-established or, if the pipes
installed in a perched manner, the pipes shall be removed and re-installed correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of
the stream up or down stream of the culvert(s). Existing stream dimensions (including the
cross section dimensions, pattern and longitudinal profile) shall be maintained above and
below locations of each culvert. Therefore, you must provide plans with adequate details
that indicate that the current stability of the stream will be maintained or enhanced. You
must receive written approval from this Office for the above plans before the culvert(s) is
installed. Culvert(s) must be installed according to approved plans.
Placement of culverts and other structures in waters, streams, and wetlands must be placed
below the elevation of the streambed by one foot for all culverts with a diameter greater
than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less
than 48 inches, to allow low flow passage of water and aquatic life. Design and placement
of culverts and other structures including temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or
banks, adjacent to or upstream and down stream of the above structures. The applicant is
required to provide evidence that the equilibrium shall be maintained if requested in writing
by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable instead of rip rap or other bank hardening
methods. If rip-rap is necessary, it shall not be placed in the stream bed, unless specifically
approved by the Division of Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicant shall complete and return the enclosed
"Certificate of Completion" form to notify NCDWQ when all work included in the §401
Certification has been completed. The responsible party shall complete the attached form
and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon
completion of the project. Please send photographs upstream and downstream of each
culvert site to document correct installation along with the Certif cate of Completion form.
